Seriously, the film reflects poverty problem in the third world! The poor are marginalized, like in the film Stephen Chow and his son is boycott by the rest of the world. His son can only gain his happiness or revive his self-esteem through a toy that comes accidentally from outer space, something unrealistic. What's lucky is they still have their own world and they know how to entertain themselves within their 'home'. Their 'home' is like a spaceship: Stephen Chow and his son are like aliens to the prosperous world nowadays. They are often ignored and even looked down upon by the others. They do not have their position in the realistic world unless by the help from something unrealistic.
